Circuit is a theme for consumer electronics shops that sell phones, laptops, headphones, wearables and accessories. It keeps the look of a classic electronics store: white pages, black rounded hero tiles, a centred wordmark over a row of category icons, uppercase section titles and large, clear prices. The home page has a slideshow, two feature tiles, a moving ribbon, a brand logo row, featured products, a category grid, a phone comparison table, image with text, an FAQ, feature boxes and guides from the blog.

Product pages are built from blocks you can reorder or remove: breadcrumbs, title with SKU and vendor, rating, price with tax note, volume pricing that highlights as the quantity changes, a bordered list of service points, colour swatches and storage pills, quantity, Add to bag and Buy now, wishlist and compare, back-in-stock alerts by email or text, delivery notes, and an Ask a question form. Specifications, what is in the box, care notes and the manual link come from product metafields and hide when they are empty. An accessories block adds chargers, cases and cables as their own cart lines. There are three page layouts and four gallery layouts, a full-screen photo viewer, and app blocks.

Shoppers can compare up to four products side by side from any product card or page, with an option to show only the rows that differ. Collection and search pages show filters for every filter type the store sets up, including swatches, pills, toggles and price ranges, as a sidebar or a drawer, with sort, grid density and paging. Product cards come in three styles, and image ratio, hover image, vendor, rating, swatches and quick add are theme settings.

After Add to bag, the theme opens the cart drawer, shows an added-to-bag card or a toast, or goes to the cart page, as you choose. The drawer and cart page show free-shipping progress from your shipping settings, the order note, discount codes, free gifts and bundle suggestions from your discounts, and gift card recipient details. Reviews follow the store's review settings, including photos, store replies and helpful votes.

For stores that sell in several countries, Circuit shows a country suggestion as a corner card, a top bar or a centred dialog, a country and language chooser with flags and currencies in the top bar and footer, and a country page. Every phone field has a country picker with dial codes, and sign-in shows the methods the store has turned on.

The theme ships with three styles: Circuit (white with black tiles), Graphite (dark) and Signal (white with blue). It includes two header layouts, three footers, and sections for a slideshow, feature tiles, ribbon, logos, featured products, collection list, comparison table, image with text, feature columns, video, banner, rich text, FAQ, newsletter, store reviews and a visit-us block.
